VB.NET

Public Class XRBinding
    Implements IXRBinding,
               IXRSerializable,
               IDisposable,
               ICloneable,

The following members return XRBinding objects:

• XRBindingCollection.Item[String]

Remarks

Use the XRBinding class to create and maintain a simple binding between an object’s property and a property of the control that represents the XRControl class or one of its descendants.

Example

The following example demonstrates how to create a binding of the XRBinding class, and add it to a control’s binding collection. The constructor method takes four arguments:

• “Text” - the name of the control’s property to be bound,
• dsOrders1 - the data source used,
• “Orders.OrderDate” - a string containing a navigation path resolving to the property of an object,
• “{0:MM/dd/yyyy}” - a string containing the bound value’s format (date/time format in this case).

Note that for this example to work correctly, a report must contain the dsOrders dataset, which should use data in the Orders table (“SELECT Orders.* FROM Orders”) from the demo Northwind database (nwind.mdb file located in the directory, where you installed DevExpress demos).

C#

using DevExpress.XtraReports.UI;
// ...

public XRLabel CreateBoundLabel() {
    // Create a label.
    XRLabel label = new XRLabel();

    // Create a data binding object.
    XRBinding binding = new XRBinding("Text", dsOrders1, "Orders.OrderDate", "{0:MM/dd/yyyy}");

    // Add the data binding to the label's collection of bindings.
    label.DataBindings.Add(binding);

    return label;
}

VB.NET

Imports DevExpress.XtraReports.UI
' ...

Public Function CreateBoundLabel()
    ' Create a label.
    Dim label As New XRLabel()

    ' Create a data binding object.
    Dim binding As New XRBinding("Text", dsOrders1, "Orders.OrderDate", "{0:MM/dd/yyyy}")

    ' Add the data binding to the label's collection of bindings.
    label.DataBindings.Add(binding)

    Return label
End Function
